Placement group IDs consist of the pool number (not pool name) followed
by a period (.) and the placement group ID--a hexadecimal number. You
can view pool numbers and their names from the output of ``ceph osd
lspools``. For example, the default pool ``rbd`` corresponds to
pool number ``0``. A fully qualified placement group ID has the
lspools``. For example, the first pool created corresponds to
pool number ``1``. A fully qualified placement group ID has the
following form::

During the backfill operations, you may see one of several states:
``backfill_wait`` indicates that a backfill operation is pending, but is not

but couldn't be completed due to insufficient storage capacity. When a
placement group cannot be backfilled, it may be considered ``incomplete``.
Ceph provides a number of settings to manage the load spike associated with
reassigning placement groups to an OSD (especially a new OSD). By default,
``osd_max_backfills`` sets the maximum number of concurrent backfills to or from
an OSD to 10. The ``backfill full ratio`` enables an OSD to refuse a
